Karen Hopkins, in Grand Isle, Louisiana, has been sick since the middle of May. "I started feeling exhausted, disoriented, dizzy, nauseous, and my chest was burning and I can’t breath well at times," she said. ...

Dean Blanchard, who runs a seafood distribution business in Grand Isle, is Hopkins' boss. He too is experiencing similar symptoms.

"They [BP] are using us like lab rats," he explained, "I'm thinking of moving to Costa Rica. When I leave here I feel better. When I come back I feel bad again. Feeling tired, coughing, sore throat, burning eyes, headaches, just like everyone around here feels."
